Enum Trit 

#[repr(i8)]
pub enum Trit {
    N = -1,
    Z = 0,
    P = 1,
}

A single balanced ternary property. Analogous to a bit in binary, just with three states: N, Z and P.

Variants

N = -1

Trit value referring to, negative, -1 or unknown

Z = 0

Trit value referring to, zero, 0, blank or false

P = 1

Trit value referring to, positive, 1 or true

Implementations

impl Trit

pub const fn new(val: i8) -> Self

Construct a new trit using an i8

For untrusted input, use TryFrom<i8>.

pub const fn value(self) -> i8

Return value as i8 for a trit

pub const fn negate(self) -> Self

Return the opposite (negated) for a trit

pub const fn abs(self) -> Self

Return the absolute value (no negatives) for a trit

pub const fn inc(self) -> Self

Return the incremented value for a trit, wrapping P -> N.

pub const fn dec(self) -> Self

Return the decremented value for a trit, wrapping N -> P.

pub const fn sign(self) -> Self

Return the sign of a trit (returns itself)

It’s implemented here, for compatibility with Word27 and other types

pub const fn is_zero(self) -> bool

Return whether a trit is zero (0)

pub const fn is_positive(self) -> bool

Return whether a trit is positive (+1)

pub const fn is_negative(self) -> bool

Return whether a trit is negative (-1)

pub const fn tmin(self, other: Self) -> Self

Tritwise minimum (follows Kleene AND logic).

pub const fn tmax(self, other: Self) -> Self

Tritwise maximum (follows Kleene OR logic).

pub const fn tnot(self) -> Self

Tritwise NOT (follows Kleene NOT logic).

pub const fn clip(self) -> Self

Returns the sign of a trit (returns itself)

pub const fn add(self, other: Self) -> (Self, Self)

Single-trit addition. Returns (sum, carry).

The carry must be propagated by the caller into the next trit position.

pub const fn consensus(self, other: Self) -> Self

Consensus: Z if either is Z, P if equal, N if opposite.

Trait Implementations

impl Clone for Trit

fn clone(&self) -> Trit

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Trit

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for Trit

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl From<Trit> for i8

fn from(t: Trit) -> Self

Converts to this type from the input type.

impl Hash for Trit

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for Trit

fn cmp(&self, other: &Trit) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

impl PartialEq for Trit

fn eq(&self, other: &Trit) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

fn partial_cmp(&self, other: &Trit) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.

type Error = &'static str

The type returned in the event of a conversion error.

fn try_from(val: i8) -> Result<Self, Self::Error>

Performs the conversion.
